autocompletion putting space after method name

It seems like the autocompletion when pressing Tab for methods that take multiple parameter lambdas inserts a space after the method name before the parentheses even though the Advanced Setting for no space after method name is set. This does not happen for methods that take a single parameter lambda.

It also seems that methods that take parameters that are not lambdas don't get autocompletion of parentheses at all?
